Windows xp Taskbar icons

Question

I am running XP SP2 Media Edition and when I minimize a Windows Explorer window, I can only see the First letter of the minimized window. Minimized Browser windows will show the complete title. I have tried several Taskbar repair routines with no success. What can I do to restore the full description of the minimized window in the taskbar icon. (I have tried also, several restores to earlier setpoints with no success as well)
